Quality Control

Our Lanthanum Bromide is produced under stringent quality management systems to ensure batch-to-batch consistency and high chemical purity. We employ advanced analytical techniques, including Inductively Coupled Plasma (ICP) and titration methods, to verify composition and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and trace metal content is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place under an inert atmosphere or in a desiccator to prevent moisture absorption. Recommended long-term storage temperature is 15-25°C. Handle and open containers in a controlled, dry environment.
